Designated Slave Flash

If using two or more EF-530 DG Super flash units, you can designate which flash will fire together by using the channel settings. In this mode, one flash unit will be used as the Slave Controller and the others for firing as Slaves.

Setting the Slave Flash unit(s) for firing

1.Attach the slave unit to the camera body.

2.Set the camera’s exposure mode to S or M.

3.Set the shutter speed to 1/30 or slower. (The slave controller unit (Master Flash) will transmit the designated signal before the others fire. Thus if you use a shutter speed faster than 1/30, the firing flash units will not be synchronized.)

4.Switch “ON” the flash unit and press the camera’s shutter button halfway. (The aperture value and film speed are now automatically transmitted to the slave flash unit.)

5.Remove the slave flash unit from the camera.

6.Press the MODE button and select the / . (Slave Mode)

7.Press the SEL button to make the channel display indicator blink.

10.Press the + or – button to set the flash output amount.

◆Set the flash power by setting the distance indicator on the LCD panel to coincide as closely as possible with the actual distance from the slave flash to the subject. If the actual distance is out of range, you need to change the aperture value.

11.Press the SEL button several times to make the display stop blinking.

12.Place the slave unit in the desired location. Do not place the slave unit within the picture area.
